I17 1.0 aZZ 2072/0122 2.15 may concern.-

Beitknown that I, ALEXANDERC. McOLEn LAND, a citizen of the UnitedStates, residing at Island City, in the county of Union and State ofOregon, have invented a new and [mproved Grain-Drill, of which thefollowing is a full, clear, and exact description.

Seed-drills have been provided with revolving concave disks orplate-wheels for opening afurrow, and aseed-tube or boot has beenarranged on one side of such disks for the purpose of delivering graininto the furrow formed by it.

My invention is an improvement in this class of seeddrills, and in placeof making the furrow-opening disk concave, (which is objectionable forseveral reasons) I employ a flatsided disk, and combine with it a platewhich is in contact with it at the forward edge, but separated at therear side, so that they co-opcrate to form the furrow. For convenienceof description, and asindicative of the main function of said plate, Ishall hereinafter term it the furrow-opener.

The several features of invention will be hereinafter described andclaimed.

In the accompanyingdrawings, Figuresl and 2 are opposite side elevationsof a portion of a grain drill, one of said views showing thefurrow-opener broken away, disclosing theforwardly-inclinedgrain-conductingplateapplied to said furrow-opener.Fig. Pisafront view of thefurrow'openeranddisk,thedraft-bars being insection. Fig. 3 is a vertical section on line 00 m, Fig. 1. Figs. 4 and5 are detail views of the boot or seed-tube and the grain-conductingplate. Fig. 6 is a side view of the furrowopening plate detached.

In the organization of my invention I employ a boot or tube, A, whichtakes the grain from the seed or grain box, (not here shown,) and whichis suitably connected, it may be, as shown, by a bar, a, and a bracket,to, to the front cross-bar, a", of the machine. The lower end of theboot or tube A is provided upon its under side with a reducedwedge-shaped pendant or projection, A, with its apex or tapering edgenext to the forward end of the machine.

B B are two plate-like bars having their forward ends connected, it maybe, by a common bolt to a bracket or lug, Z), pendent from Serial No.215.0716. (No model.)

the cross bar a One of these bars, B, which, in common with the otherbar, B, has its forward portion inclined downwardly and rearwardly, isextended horizontally from its inclined portion, and is bolted at theext reme rear end of said horizontal portion to one side of said wedgeshaped projection or pendant A. The bar B will be further referred tohereinafter.

Ois the fnrrowopcner, which is connected to the opposite side of saidwedge-shaped projection or pendant A, the same bolt securing the bar Balso connecting the opener to said projection or pendant. The lower orbottom edge of the furrow-opener O is rounded or convexed, to havesubstantially a coincident curvature with the periphery of the disk orwheel, presentl y described, whereby jointly they form the furrow forthe reception of the grain passing from the boot or tube down betweensaid wheel or disk and opener.

D is the wheel or disk, which is borne by an axle, 0, formed with andprojecting from one side of the furrow-opener O, and toward which wheel,near its forward and bottom edge, by reason of the inclination of thewedge shaped projection or pendant, the latter is caused to approach orconverge, thus enabling the wheel and 'l'urrow-opener to have aplow-like action upon the soil, to form, as above recited, the furrow.To the outer or one end of the axle c, which projects considerablybeyond the disk or wheel D, and which is provided with a sleeve orthimble, 0, is connected the bar B, as is also a second plate-like bar,B. The bar B is connected at its upper end to the bracket (1, the lowerend of said bar resting against the outer end of the sleeve or thiinble0, thus serving, with the bar B, to properly support that end of theaxle in position. The bar B is ex tended inwardly, rcarwardly, anddownwardly from the axle 0 into ascraper, B, the extreme lower endthereof terminating at a point contiguously to the rear lower edge ofthe periphery of the Wheel or disk D, in order to remove or detachadhering dirt from the latter.

F is an adj listing-screw applied to the bar B and hearing at its innerend in the bar B. By operating or turning said screw so as to draw thebar B inward, which in turn draws upon the axle c, carrying the wheel ordisk D to ward the furrow-opener O, the wheel or disk D l is adjustedwith relation to and caused to bear with greater or less pressureagainst the furrow'opener.

G is an angular plate, with its Wing gbolted to the inner side of thefurrow-opener C, so as to dispose the same in aforwardly-inclinedposition, the main-portion, 9, thus forming a conduetor for the grainfalling from the boot or tube A to the furrow.

This invention serves to form the furrow, while it conducts the grain toits destination and avoids side draft.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1.- In agraindrill, the combination, with the wheel or disk and thefurrow-opener, oi the plate-lil e bars and the adj listing-screw adaptedto bring the wheel or disk toward or against the opener, substantiallyas set forth.

2. In agrain-drill, the combination, with the boot or tube having at itslower end a wedgeshaped projection depending from its under side, of thefurrow-opener secured to one side of said projection and the wheel ordisk, substantially as set forth.

3. In agrain-drill, the combination, with the boot having at its ]owerend a wedge-shaped projection depending from its under side, of 30
